Nite Burn or Deficiency?

3rd week into flower and this girl was doing great until about 5 days ago. Random leaves lost color and now Brown spots, edges, and tips turning brown. It's affected the plant all over really not in any one particular spot. Anyone have any ideas? Going to do a flush next just to get things straight again. Any help would be sweet!

dont flush . cut those old leaves off, they're done photosynthesizing, its natural. double check your nutrient supply temperatures humidity and air movement, if all those are correct then everything is good

Most of the leaves are midway up on the plant? I thought removing those leaves wasn't a good thing because they supply the bud sites with what they need throughout flower? I would say at least 60% of the leaves have the brown edges and tips.

ok, some on the bottom like this is no worries, but ....

start with feed, ph ?

Chronic under watering. Possible root bound.

PH is around 6.3. I have been feeding it a 1-3-2 ratio flower food for only a week now. It may be rootbound but I couldn't transplant again due to growing space so I figured I would ride it out. I know it's not underwatered I actually had a problem with over watering while in veg. Is my plant toast? This is my first grow and all was going well until this haha.

Looks to me like some calmag def

Are u supplementing calmag?

No I'm not. That's what I thought originally what it was. But then also think I may have over fed and have nute lockout. Think the best plan would be to flush and then start back up with 1/4 strength nutes and maybe supplement with cal mag?

Or continue with what I'm already doing and just supplement the cal mag in? First grow so don't know much on helping burnt or hurt plants haha

Will be great to know what u have been doing since the beginning like water/feeding schedule, how much how often, type of soil, ph ,rt, rh, etc etc. The more info the better the help..

root bound? I dont recall growing or flowering any potted plant that wasnt root bound.
Grown 5 foot trees in one gallon bags with no issues too. prolly some other issues going on imo

Are the healthy leaves bendy or slightly crispy? Are the slightly affected leaves bendy or crispy?

Both healthy and slightly affected leaves are healthy and bendy. None of them snap or are brittle at all. I flushed is last night with 6 gallons of PH water as I have her in a 2 gal pot. Hopefully the problem doesn't worsen!
